Most of that mushy feel comes from the subframe mounts. Our ZL1 uses the same durometer rear subframe bushing as the 2012 V8's as far as we can tell. Honestly if you're going through the hassle of dropping the rear subframe to swap mounts out you should probably do it once, and do it right the first time. Our Solid Subframe Mounts really do make a massive difference in the feedback and performance from the rear end of the car, without significant impact to ride quality. If you move to a stiffer poly replacement for the differential mounts that can definitely run the risk of increasing noise from the differential, but the subframe mounts are pretty quiet and will definitely accomplish what you're looking for.

Do you have to drop the whole rear subframe to do a gear swap? If you do, then putting in the Pfadt bushings at that time would be a really good investment.

Correction Pfadt, the ZL-1 has stiffer durometer cradle setup than my 2012 ss. Pedders mentioned this months back and I proved this for my self with a ZL-1 on the showroom floor. But the Pfadt cradle bushings would be still superior.

Is this just the gear pieces or the whole pumpkin. Would the 1LE pumpkin fit our SS.

Just the gears. Not sure that there is anything else different inside the housing. All the info I've seen on the package has talked about the new rear gears and new axles. I haven't seen anything indicating anything else inside the diff case has changed. Yes it would fit, just not sure why you would need the whole thing.

I thought the 1LE had a diff with a diff cooler. This would also be a good upgrade having a cooler diff for road course stuff.

I haven't seen that. Nobody has actually worked on one yet, probably will know more as they start to get delivered. But the only difference in the rear diff that I can see is the R&P gear. The 1LE case and diff carrier are the same part numbers as the SS w/o 1LE.

Awesome, looks around $1300 to my door. Since you don't have to pay a core, that's a really good price.

Wouldn't someone just need the gears? Just curious about the interest in the whole rear for an SS. I'm doing the 3.91s soon, want to make sure I'm not missing something. So far my plan is just the gears, axles, hubs, pinion crush sleeve and shim kit.

I'm also trying to figure out what if anything is different about the 1LE driveshaft. Possibly the bolts?
